All eight trains of the Nhon-Hanoi Station metro line went on a test run on Monday, according to the Hanoi Metropolitan Railway Management Board.

The test run will be conducted in two phases, with the first phase lasting from five days to six weeks in order to evaluate the line's RAM efficiency. During the first phase, four to eight trains will run between 9 a.m. and 7 p.m.

If the efficiency recorded during the first five consecutive days of trial runs failed to reach 98%, the trial run will be extended until the goal is achieved, to the maximum of six weeks.

During the test run, the entire system will operate as a whole, with trains running the 8.5 km elevated section from Nhon depot to S8 station. Each train would stop at a station for about 20 seconds. The entire time it takes for a train to run between two ends would be around 16 minutes, meaning a round trip would take 32 minutes.

The second phase of the trial run would happen right after the RAM efficiency evaluation is completed, with several scenarios being simulated, such as blackouts and fires.

The Nhon-Hanoi Station, scheduled to be the second metro line to start operation in Hanoi, will run 12.5 km from Nhon in the western district of Nam Tu Liem via Kim Ma Street to the downtown Hanoi Railway Station.

Work on it began in 2010 at an estimated cost of $1.2 billion, but several delays pushed it up to almost $1.5 billion.

The line's first train was put on trial run in January last year.

The city's first metro route, Cat Linh - Ha Dong, also the country's first, started running November last year.
